It's extremely important that kids have motivation to learn Persian. How
to increase their motivation is not as difficult as you might think.You
can simply do the following

1-Rewards

Offer them rewards for learning extra words or phrases (e.g. a chocolate
bar from Persian, a trip to a Persian restaurant, or his/her favorite
place, such as zoo, museum, playground or an amusement park)

2-Surprises

Especially for small children, including infants and toddlers, surprises
are proven to increase motivation. If you play surprising games your
child will be able to keep paying attention to the program.

3-Fun & Games

Playing games like hide and seek by counting in Persian, online memory
or matching games or puzzles, and cardboard games will do the trick.

4-Keep it short and simple

Not only adults but also children automatically lose interest if what
they are asked to do is difficult. When you ask them to learn only a few Persian words at a time, they will find the task more enjoyable and
increase their confidence in learning Persian.

Practice, Practice, Practice

Practice makes it perfect the old saying goes. If your child has no
opportunity to practice what he/she learned, you can make sure that all
the efforts are in vain.

5-Flash cards & posters

Flash cards might sound like an old school method but they are very
effective. Similar to Dino Lingo motion images, how flash cards work is
very simple: they create object-sign associations in your child's brain
after a short period of exposure. You can use Dino Lingo flash cards or
make your own flash cards and practice with your child.

6-Cartoons

Children love watching cartoons. You can find tons of Persian cartoons
available online also Dino Lingo Persian program has perfect combination
of cartoons.

7-Story books

If your child knows some Persian, you can purchase Persian story books
on the internet. If he/she doesn't know how to speak Persian, you can
read fairy tales by replacing some words with Persian words.

8 -Music & songs

Music is universal, and you can find many Persian songs available online
and in supermarkets. It is also not a bad idea to buy some Persian
children's song CD and play it in the car or at home as background
music. Studies have shown that even background music can increase
children's vocabulary.

9-Talking with native speakers

One of the best ways of practicing Persian is giving your child
opportunities to interact with Persian native speakers. It would also
be
a fun family activity to visit a place where Persian is spoken such as
a Persian restaurant, supermarket, cultural center, school, community
center etc.

10-Test & quiz

You can speak to your child in Persian if you know how to speak Persian.
If you don't know how to speak Persian, you can still ask questions
like "what is "this" in Persian?" by showing an object. If you know a
few words in Persian, you can show him/her two objects and ask "which
one is "…". Kids also love drawing things, you can also play with your
children and ask them to draw objects by calling object names in Persian, like; "can you draw me a …?".

Summary: Kids love watching Dino Lingo DVDs regularly and play Dino
Lingo online games. Visit places where Persian is spoken. Play with fun
educational stuff like Persian jigsaw puzzles and Persian toys. Don't
forget the posters (Persian alphabet, sight words, flag, map). Interact
with other kids who can speak Persian or studying together with someone
with whom they can practice Persian.
